python3 時間戳和時間的一些轉化

1.時間日期轉時間戳

import datetime
now = datetime.datetime.now()#datatime類型
time_stamp = time.mktime(now.timetuple())
print(int(time_stamp))#秒級

2.時間字符串轉時間戳

st = time.strptime('2018-10-07 16:12:54', '%Y-%m-%d %H:%M:%S')
time_stamp = time.mktime(st) 
print(int(time_stamp))#秒級

3.直接生成當前時間戳

import time
time_stamp = int(time.time())
print(time_stamp)#int

4.時間戳轉時間字符串

ltime = time.localtime(1552723974)
time_stamp  = time.strftime('%Y-%m-%d %H:%M:%S',ltime)
print(time_stamp)#str
